Library /sys$common/syshlp/mailhelp.hlb SET-SHOW, FORWARD, Qualifiers  *Conan The Librarian (sorry for the slow response - running on an old VAX)

1 - /ALL

    The /ALL qualifier lists forwarding information or displays a
    message if the specified user does not have forwarding enabled.
    You must have SYSNAM privilege to use the /ALL qualifier. The
    /ALL qualifier is valid only when used with the /USER qualifier.

2 - /USER

       /USER=user-name

    Indicates the name of another user for whom you are setting or
    showing a forwarding address. You can use the /USER qualifier
    only if you have SYSNAM privilege. With the SHOW FORWARD command,
    there are two ways to show a user's forwarding address: you can
    specify the user name or you can use the wildcard characters (*
    or %) to search for names with a particular string in common.
